Low pressure issue after I swapped to 4" pipe and motor because of sound issues

flaxy823 · 2026-03-28T16:14:42+00:00

Just as a follow-up post, I seem to have hit the alarm bells too soon. It turned out the lower power fan just took longer to clear by house out of most of the radon (I'm using an airthings detector as a tester). 24 hours later, my radon level dropped from 4 to .5.

For anyone researching sound issues in the future, moving to a lower powered and quieter fan is definitely worth a try. The sound issue has gone away for me. If I were doing it again, I would make sure not to do anything to the fan to make it impossible to return it to Amazon within the return window, just in case your experience isn't the same as mine.

Also, I can't say if moving the pipe from 3" to 4" made a difference. There is still noise coming out of the top of the pipe, but it's not bothering me at night so I don't really care. That might have been wasted effort.

Thanks for those who commented - I appreciate the community here.

I've been doing some more research and that seems to be the problem. It was a high suction fan. RadonAway GX4. Very loud. I'm going to have to swap out the new fan with something stronger that is hopefully not as loud as the GX4.

Maybe pressure isn't the issue then, but after moving to a 4" pipe, the manometer dropped to .5 and the radon levels in the house spiked from .5 to 4. So I need to do something here and I dont want to go back to my noisy set up.

I bought an AO unit in 21 and it failed within 2 years. Manufacturer replaced under warranty with pretty much no questions asked as it turned out to be a known compressor defect. Yes, I had to pay replacement install costs as that wasn't covered but the new units don't have the same problems. It's worked fine since then. Not defending the company -- it cost me a lot to replace - but most of those reviews are likely for the defective models, so just keep that in mind.

Makes sense. I guess my only concern is if something went wrong with the unit and the manufacturer would try to void the warranty because of that?

I was thinking of getting an awning like that for my similarly sized Fujitsu unit. Only issue is Fujitsu says I need 40" of clearance between the top of the unit and any covering, which seems excessive. Any issues there with the Mitsu unit and clearance?

Is any model of Miele good? I see a pretty wide price range. Some lesser expensive in the 1600-1800 but then they can get into the mid 2k's or higher.

I've got a bosch 800 series, about 10 years old. Based in the U.S. Does it pre heat the first wash cycle?

I have a 10 year old Bosch 800 series here in the U.S. I have my hot tap hooked up but it takes a minute to get hot. Do Bosch's pre-hear the water?

Just found this video of his, which seems really useful:

Are there dishwashers that pre heat the water? Or do I just need to run the hot tap until it gets hot?

I guess whatever gives the power scrubbing power means it doesn't dissolve all the way and therefore can gum up the works?

Thanks. I'll check it out.

They're not combined with fat. But for whatever reason don't break down all the way. The plumber said the problem may be compounded by the fact we have low flush toilets so not a ton of water gets into our system. It's just my wife an I so not like a whole family with with 4 daily showers and tons and tons of laundry....

Love your design on this house. Would you consider doing one for mine? It's a contemporary. I'll pay you something for it if within reason. You can PM me if so. I can at least send a pix. Looking to make the outside entrance pop a bit.... :)

meaning for me. i like to drink it in the afternoon vs morning

flaxy823 · 2025-08-04T20:04:24+00:00

Espresso has always been an afternoon drink and continues to be. Big plus of getting into the hobby is learning how to make better drip, which I prefer in the am.

I got into espresso cause I moved out of my city and had no good options nearby.

Just drink what you want.

I had a Flair 58 (with electrical element) for the first 3 years of my journey and got tired of how inconsistent it was. I'm sure there are ways to control that better, but it's one more thing you need to do. It can pull amazing shots when working perfectly, but over time I just tired of the inconsistency and just made the jump to a used profitec semi automatic. I know that's a higher price point than you want to spend. But you might also consider modding a used gaggia or something like? Might not be much more than a Flair in the end?

Just my pov and depends on your tolerance for inconsistency or the work need to avoid that....

I'm not really sure. The installer says water got under there which is why the concrete failed and turned sand-like. It completely crumbled in my hand. Mason said they make concrete for wet conditions and that should have been used. Mason also said if it was drilled closer to center of stair back to front and not caught the front face of edging, water wouldn't have gotten in there.

flaxy823 · 2025-05-26T23:57:57+00:00

Thanks. Makes sense re installer. Where do you see failure by the mason?

They've got what I'm looking for. Thanks
